我们研究了通过弹簧耦合连接的两个极限环MEMS振荡器的动力学。每个单独的振荡器都基于MEMS结构,该结构在激光驱动的干涉模式中移动。当结构振动时,它改变了干涉间隙,引起吸收光的数量变化,在运动和吸收光之间产生反馈回路,导致极限环振荡。先前已经提出了该MEMS振荡器的简化模型,省略了参数反馈和结构阻尼(Rand等人在第九届欧洲非线性动力学会议(ENOC 2017), 2017,[3])。对于耦合系统,采用摄动法求解慢流,并采用AUTO和数值积分法对慢流进行了研究。确定了由于耦合强度变化而产生的各种分岔。
We investigate the dynamics of two limit cycle MEMS oscillators connected via spring coupling. Each individual oscillator is based on a MEMS structure which moves within a laser-driven interference pattern. As the structure vibrates, it changes the interference gap, causing the quantity of absorbed light to change, producing a feedback loop between the motion and the absorbed light and resulting in a limit cycle oscillation. A simplified model of this MEMS oscillator, omitting parametric feedback and structural damping, has been previously presented (Rand et al in Proceedings of 9th European Nonlinear Dynamics Conference (ENOC 2017), 2017, [3]). For the coupled system, a perturbation method is used to obtain a slow flow which is investigated using AUTO and numerical integration. Various bifurcations which occur as a result of changing the coupling strength are identified.
